OG 12 DS #166

If n is a positive integer is (1/10)^n < 0.01? (1) n > 2 I can understand why (1) is sufficient (2) (1/10)^(n-1) < 0.1 But for statement 2 If I plug in 1 for n then (1/10) ^0 = (1/1) = 1 which is greater than .1 If I plug in 2 for n then (1/10)^ 1 = (1/10) = .1 which is equal to .1 If I plug in 3 fo...

I picked D at first then I saw the OA as C. I can see why. The fact that the militairy no longer requires immunization shot for it's pilots despite a growing threat appears to be contradictory. That can only mean that the real reason is to support the argument in reducing accidents.[/spoiler]

20 + p(20) = 20 + 20p
60 - p(60)= 60 - 60p

20 + 20p = 60-60p
80p = 40
p = 40/80 = 1/2

p% of 70 is 1/(2/100) = 1/200 * 70 = 70/200 = 7/20 = 35%

I think it is C because from the sequence it shows that A through the process will always lead to D. Hence If D does not exist then A was never there. Because if A were there then it would lead to B, then C and then D. But if there is no D then there was no A. I know it is real confusing but hope I...

I'm trying a different approach to solution 2. Please comment as to whether this is accurate; Thanks. 5^(k-1)= 5^k - 500 *5^(k-1) is the same as (5^k/5^1)* so (5^k/5^1) = 5^k - 500 *Next move the 5^K to the left hands side from the right hand side* so (5^k/5^1) - 5^k = -500 * Then multiply each term...

A)3x^2-x+2

E)3x^2-2

Re: WORD PROBLEM

I've found that some of these inequality problems often introduce a level of ambiguity making them insufficient. Anytime you can refute the established case, or establish a case that contradicts the earlier case, the answer is going to be insufficient. b = Boys g = Girls b > g? (1) g < 3b b= 5 3b = ...
